Emissive Display Driver Layout With Shared Input Signal Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emissive display devices have a significant non-display area that is not utilized efficiently, leading to increased size and complexity.
Innovation Solution
The emissive display device incorporates a driver structure where multiple signal stages are connected in common with input signal lines, allowing for symmetrical arrangement of drivers alongside the display area, reducing the non-display area by sharing signal lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple drivers are disposed in the non-display area, then the display function is improved, but the non-display area width increases
Solution Approach 1:
Multiple drivers are merged into a single non-display area by sharing common input signal lines. The first driver and second driver both connect to the same input signal line, allowing them to be disposed within the same non-display area rather than requiring separate areas for each driver.
Solution Approach 2:
The input signal line serves multiple functions by being commonly connected to both the first driver and second driver. This multi-functional signal line enables a single input signal line to control multiple drivers, reducing the need for additional dedicated signal lines.
2Reliability
If separate input signal lines are provided for each driver, then signal transmission reliability is improved, but device complexity increases
Solution Approach 1:
Multiple input signal lines are merged into a single common input signal line that serves both drivers. This reduces the total number of signal lines from two separate lines to one shared line, simplifying the overall device structure.
Solution Approach 2:
The common input signal line is designed to universally serve multiple drivers simultaneously. This multi-functional approach allows a single signal line to perform the role of multiple dedicated lines, reducing device complexity while maintaining signal transmission capabilities.

AI summary
An emissive display device includes a display area which includes a plurality of pixels, and a driver disposed at a side of the display area, where the driver includes at least two emission signal stages disposed in one row, and an input signal line connected to the emission signal stages, and the at least two emission signal stages are connected to the same input signal line.
